1969 Map of Petrolia

USGS Topo · Published 1974

About this map

Petrolia serves as the focal point for this 1960s survey of the Humboldt County coast, noted prominently as the site of State Historical Mon 543 First Oil Field in California. The landscape is defined by the winding course of the Mattole River as it approaches the Pacific Ocean near Mattole Point. The inland terrain is marked by sharp ridgelines like Shenanigan Ridge and Prosper Ridge, which drop steeply toward the sea at Punta Gorda.
